My boy Bernie arrived at our house, age 2, fully intact. We had him
neutered as part of the adoption contract, but ... he continued to hump
(and I mean all the way to a little doggie howling climax) for about 6
years. Thankfully the frequency has finally diminished to near zero. It
started out several times per day and always when company was here .... the
sound of happy conversation served as some kind of an aphrodesiac for him.
What an embarassment! I would have to tell him to "get a room" and
remove him to an empty part of the house. :) Man he was a sex fiend.
I've heard that chihuahuas are "worse" this way than some other breeds.
Can anyone confirm?
